Acquired Patella Baja After Total Knee Arthroplasty May Be Caused by Patellar Eversion
Richard Laskin; Markus Floren; Jack DavisKnee
Acquired patella baja occurs after many orthopedic procedures including total knee arthroplasty (TKA), with prevalences between 30% and 60%. The inferior position of the patella leads to alterations in the joint mechanics, reduction in range of motion, and anterior knee pain, and can cause increased wear of the tibial and patellar polyethylene. Our aim was to evaluate the prevalence of patella baja after TKA and to assess whether this was affected by displacing rather than everting the patella.
